How long does non-pasteurized draft beer typically last before expiring?

Non-pasteurized draft beer typically lasts around 45 to 60 days before it begins to lose its freshness and flavor. The process of pasteurization helps to kill bacteria and extend shelf life, but non-pasteurized beer relies on proper storage and handling to maintain quality. Exposure to light, temperature fluctuations, and oxygen can all contribute to a faster degradation of the beer. Therefore, the understanding of the limited lifespan of non-pasteurized draft beer emphasizes the necessity for bars and restaurants to manage their inventory effectively, ensuring that customers always receive the freshest product possible. This timeframe aligns well with the general brewing guidelines, establishing a standard for freshness that brewers and retailers consider in their operations.
